GENERAL DESCRIPTION
The AD862x is a precision JFET input amplifier. It features true single-supply operation, low power consumption, and rail-to-rail output. The outputs remain stable with capacitive loads of over 500 pF; the supply current is less than 630 uA/amp. Applications for the AD862x include photodiode transimpedance amplification, ATE reference level drivers, battery management, both line powered and portable instrumentation, and remote sensor signal conditioning, which includes automotive sensors. The AD862x's ability to swing nearly rail-to-rail at the input and rail-to-rail at the output enables it to be used to buffer CMOS DACs, ASICs, and other wide output swing devices in single-supply systems. The 5 MHz bandwidth and low offset are ideal for precision filters. The AD862x is fully specified over the industrial temperature range. ( 40 C to +85 C). The AD8627 is available in both 5-lead SC70 and 8-lead SOIC surface-mount packages (SC70 packaged parts are available in tape and reel only). The AD8626 is available in
MSOP and SOIC packages, while the AD8625 is available in TSSOP and SOIC packages.
